Xcode – Apple rejects app because of AppTrackingTransparency.framework (can't find it included in the app)

Just got this message from Apple this morning:

We noticed that your Kids Category app includes analytics, advertising and collects, transmits, or has the ability to share personal information or device information with third parties. Specifically:

- Your app implements the App Tracking Transparency framework, which is used when apps collect data about users and share it with third-parties for tracking purposes. Since Kids Category apps are not allowed to collect, transmit or share identifiable information with third-parties, you should not implement App Tracking Transparency in your app.

However, having done some rigorous searching in all node_modules and pods, I cannot find any reference to the AppTrackingTransparency framework. How can I figure out where it’s included and remove it?

Most likely, either Firebase Analytics or Onesignal is including the framework. I just can’t see any reference to it anywhere.
